In response to public comments regarding the estimated economic impacts displayed in the Rosemont Copper Mine DEIS (which came from a study conducted by Applied Economics (AE)), the US Forest Service (FS) conducted their own economic impact analysis of the proposed mining project for comparison purposes. This briefing paper compares the results of the FS analysis to the AE results cited in the DEIS. It is hoped that this additional analysis will provide the public with an increased understanding of the impacts published in the DEIS.
